Rhodium is a rare, silver to white metal that comes from the platinum group in the periodic table. It is one of the most expensive metals at almost twice the price of platinum, and three to four times the cost of gold. Rhodium is extremely reflective and doesn’t normally form an oxide, even when heated.

The process involves stripping off any old Rhodium and polishing the metal, making sure there are no impurities. A thin layer of rhodium is then plated onto the surface and the finished result will be a piece of jewellery which looks as good as the day it was made.

The rhodium plating will eventually wear off and should be reapplied every few years. This will be evidenced on the portions of the ring that receive the most wear and start to look pale yellow in color instead of bright white.
